CELTA has a high profile in Europe and is undoubtedly a popular qualification that will open many doors however it is also true that in most places the basic requirements for entry level teaching positions are a degree plus a TESL/TEFL certificate - not necessarily a CELTA. A CELTA course is also quite an intensive course, worth perhaps investing into if your aim is to remain within the
ESL industry and build a career in this field. However if someone like yourself is starting up and would like to be equipped to teach around the world then a quality online teacher training course like ours will allow them to get a taster of the ELT profession and see if it is really for them before committing time, effort and finances to get to the next level.
Online courses offer a great training opportunity at entry level. They can provide a thorough grounding in a new career and the right tools to approach a new profession within a manageable amount of time and finances. Of course, check out the course and course provider first – in fact, be sure you do this with any course you decide to go for, regardless of whether it is a traditional onsite course or an online one.
I think though your main hurdle could be not having a degree, as this is often a requirement of the countries and their visa regulations. In many countries you will need to hold a degree if you want to obtain your work visa and work legally. This is especially true in Asian countries. Where are you planning to move to?
